The EN test also is performed at -18°C. The EN requirement is however split into two levels: EN1 and EN2. Size: Car batteries come in various sizes. You should know the battery size that fits into your vehicle perfectly. Consider the height and width of the entire battery and make sure it matches the car battery space in your vehicle. Buying a smaller or a bigger battery will definitely not serve you well. You might need to go through a car battery chart to know the actual size that will fit your vehicle. Sluggish Engine Crank: When you attempt to start your vehicle and you notice the cranking is slow and takes longer than usual to starts. Battery Leakage: When you constantly notice corrosion around the area the positive and negative cable connections are located, there is a battery leak.
Auto batteries are great for supplying high current in a short time but aren’t suitable for delivering sustained amps over time. If you start to notice your car’s engine isn’t quite behaving properly – for example, it doesn’t always start first time, you can hear it whirring but it doesn’t actually start or you can’t turn it on at all, it’s likely time to change your battery. Let’s focus on lead-acid batteries (still the most commonly used) and they come in two broad categories: auto batteries and deep-cycle, sometimes called ‘leisure’ batteries. Due to this relationship, we usually display SAE as our standard to minimise confusion. JIS (D5301: 1999) VARTA was founded in 1887 Germany, and was established fully in 1904 by delivering the first electric vehicle battery, famously driven by Thomas Edison. Soon after, VARTA delivers the first ever vehicle battery to provide safe night time driving with electric vehicle headlights! Today’s VARTA batteries have been providing renowned German advanced technology, powerful performance and exceptional service around the world for well over 100 years.The Ampere-Hour Capacity varies with the rate at which the battery is discharged; the slower the discharge, the greater the amount of electricity that the battery will deliver. Amps represents a typical electrical load on a car under normal running conditions, so the Reserve Capacity gives an indication of the time that a vehicle with a normal electrical load will run with a broken alternator or fan-belt. This is a good, practical test. Flat – Flat lid feature with no raised plugs which could interfere with manufacturers top clamp frame. Deep-cycle batteries don’t have CCA (Cold Cranking Amps) because they are not designed to deliver high currents for any length of time.
The Ah (ampere-hour) rating of a battery is an indication of how much energy it stores and can deliver. Alpha Batteries bears no responsibility for whatsoever for loss occurred due to late or failed deliveries. The market for car batteries has grown. New models and brands are designed and pushed to the market every day. Car batteries, like other car parts, vary in size, capacity, quality, design, and durability. Gone are the days when there were just a few brands of car batteries. Today, there are lots of brands with diverse unique car batteries out there. Faulty products will be replaced as soon as we are able to verify the fault and ship another to you.These make the battery suitable for applications in which there is some cycling (e.g. vehicles with tail-lifts). GS Yuasa Automotive Online Battery Look Up Tool Warranty: When it comes to 75 Ah batteries or any battery at all, warranty matters. Some brands offer a 12-month warranty with a free replacement when the battery develops issues within the warranty period.
The ETN (European Type Number) was introduced to replace the DIN Number during Europeanisation of Battery standards. The ETN is a combination of the DIN numbering system which facilitates the changeover and gives further technical details.Consider the age of the battery. Most batteries begin with two characters: the first is a letter, and the other is a digit. The letter usually designates the month the car was manufactured. Generally, the letter A stands for January, B for February, C for March, etc. The second character (which is usually the digit) stands for the year it was manufactured; 1 stands for 2001, 0 represents 2000, 2 for 2002, etc. Consider when the battery was manufactured before you buy one. This kind of battery has a high C rating, which is an indication of it’s ability to deliver high currents in relation to its rate capacity. Battery Leakage: When you constantly notice corrosion around the area where the positive and negative cable connections are situated, there is a battery leak, and there might be a need to change the battery. This is the starting test according to the SAE (Society of Automotive Engineers). The test specifies that the battery at a temperature of –18°C will deliver a current equal to the Cold Cranking Amps for 30 seconds with the voltage staying above 7.2 volts (3.6 volts for a 6 volt battery). A lead-acid deep-cycle battery can be discharged up to 80% of it’s rated capacity, but 50% is often recommended, as this increases the overall life.
